This Article Applies to:

All TP-Link Wireless Adapters


Problem Description:

The computer gets a very high ping value when ping gateway router;
Periodically ping spikes or freeze when playing games. 

How do I tell if the ping is high?

In gaming, any amounts below a ping of 20ms are considered exceptional, and “low ping”, amounts between 50ms and 100ms range from very good to average, while a ping of 150ms or more is deemed “high ping.” Ping measures how long it will take for the packets to be sent from the computer to the server and back, the ping result also relates to the server itself.


Troubleshooting Tips:

  • Update to the latest driver for the wireless adapter from TP-Link official website here.
  • Try a different Wi-Fi channel and lower channel width on the router.

Scan nearby wireless channels using software like inSSIDer or WiFi Analyzer and select a less-crowded Wi-Fi channel on the router.

Use lower channel width 2.4Ghz -> 20Mh, 5Ghz -> 40Mhz to reduce interference.

  • Disable VPN connections on the computer if there are any.

  • Disable other wireless adapters except for the TP-Link one.

  • Rule-out interference from other devices on the same Wi-Fi network.

Only leave the TP-Link adapter connected to the router if possible, close any background apps using the internet bandwidth, then connect other wireless devices one by one to the router to see if a certain device will cause the high ping.


Special Scenario: Realtek chip wireless adapter + 802.11k Mesh system

Ping value may rise up very high as below photo when a Realtek adapter works with a Mesh system or AP + extender using 802.11k roaming technology. 


- For Realtek USB adapters, update and install the public driver below: ( for 802.11k Wi-Fi mesh scenario only )


- Or try to turn off Mesh or fast roaming (802.11k) on the mesh system for this computer.

Here takes Deco Mesh as an example:


- For TP-Link router Archer C6, try firmware here and disable OneMesh
